Finnish company REMU is keen for its Big Float 800 floating excavator to be a splash hit following its launch this week at INTERMAT. The amphibious machine weighs in at 12,500kg and can be transported even with three-axel trucks. With a boom length of 7.7m and digging depth of 4.1m the Big Float 800, like REMU’s other Big Float models, is completely floating and can be brought to a job site by land using its tracks or towed or driven with propellers along waterways.

Hyundai used INTERMAT to show its 22tonne hybrid excavator – the 220LC-9. Designed and developed in-house with electric components from the company’s electronics division, the Hybrid 220LC uses an electric motor for its slew functions, enabling a smaller engine to be fitted.“This combination means we can use a four-cylinder 98kW engine in the hybrid compared to a six-cylinder 118kW engine in the conventional R220LC-9,” explained Hyundai product engineer Joachim Van de Perre.

Updated excavators from Hyundai Heavy Industries Europe at INTERMAT included models from 26-52tonnes. With Dash 9A status, the excavators – ranging from the R260LC-9A to the R520LC-9A – get Cummins Stage IIIb emissions compliant engines.

The new HM400-3 articulated dump truck (ADT) from Komatsu can carry a full 40 tonnes and features a host of new technology in the drivetrain and in the cab. Its 353kW engine is fitted with a diesel particulate filter with computer-controlled regeneration so that no operator input is required. A computerised Transmission Control System replaces the need for limited slip differentials in the transmission as it activates the multi wet disc foundation brakes in any wheel that starts to spin. Furthermore, the s

REMU hopes its Big Float 800 floating excavator will be a splash hit on its unveiling at Intermat 2012.

Rivard believes its RIV253 TR103 wheeled trencher can help fulfil plans to provide high-speed internet access for homes across the Republic.

Liebherr is to introduce two new tracked excavators at Intermat in April, weighing 31 and 44 tonnes respectively. The 31 tonne R936 replaces the R934C and brings with it a Stage IIIB/Tier 4i emissions compliant engine that delivers 160kW from a four-cylinder engine.

Launched just before Intermat 2012, Rivard says the company’s new RIV 503 TR202 wide offset wheeled trencher is beneficial to any large scale power cable and pipe laying project, from water and gas pipe installation to power and fibre optic cable laying.

Rivard RIV1403 TC1755 is a chainsaw trencher suitable for creating large trenches for major underground power, gas, fibre optic, water, irrigation or sewer project works.

The new Doosan DX225LCA excavator being launched at Intermat has an operating weight of between 21.5 and 23.2tonnes, depending on the configuration. Its bucket capacity ranges from 0.39 to 1.28m3. It also has a digging depth of 6,620 mm, a reach of 9,900mm and a digging height of 9,750 mm.
